According to our (admittedly unreliable and incomplete) statistics, the Mozilla Developer Center‘s English wiki received its 20,000,000th page view some time in the past day or so. This means that since initially launching on March 15, 2005, that wiki has seen an average of 40,000 page views, 70 page edits, and 5 new pages added per day.
These statistics don’t include the huge amount of incredible work the localization teams have been doing, of course, and I would like to thank them (a thousand times over) for all their help and contributions. And thanks to everyone else who has ever contributed to the project in any way. Clearly none of this would be possible without you :)
